Anal HPV Tests in Screening for Cell Changes in the Anus in Patients With HIV

PRIMARY OBJECTIVES: I. To determine the sensitivity and specificity of HPV testing using different methods of detection, including HPV Hybrid Capture 2 (HC2), HPV messenger ribonucleic acid (mRNA) assays (APTIMA) and OncoHealth HPV E6/E7 oncoprotein assay and whether they improve the screening performance of routine anal cytology for the detection of anal high-grade squamous intraepithelial lesions (HSIL) when measured against the gold standard, biopsy-proven HSIL. II. To determine the prevalence and risk factors for prevalent HSIL in HIV-infected women. III. To determine incidence and risk factors associated with anal HSIL and HPV over 2 years among HIV infected women undergoing semi-annual anal evaluations. EXPLORATORY OBJECTIVES: I. To evaluate the acceptability of anal cancer screening among HIV-infected women. II. To collect data on quality of life and health care costs (including non-direct health care costs and time costs) for an economic evaluation of the cost-effectiveness of anal cancer screening strategies in HIV-positive women. OUTLINE: Patients undergo screening for the detection of HSIL using anal cytology, HPV hybrid capture 2, HPV mRNA assays, and OncoHealth HPVE6/E7 oncoprotein at baseline, at 12 and 24 months.
